Regenerates from seed.

Shrub 1.5–6 m tall. Leaves dorsiventral, 6–28 cm long, usually entire and linear, 0.7–2.5 mm wide, rarely some or all leaves 2–7-sect with ascending linear lobes 1–2 mm wide, rarely lower lobes again divided; margins tightly and smoothly to angularly revolute; surfaces dissimilar, with lower surface sericeous or often enclosed except for midvein and then 2-grooved. Conflorescence terminal, erect, paniculate with 5–12 (–20) ascending to spreading branches, occasionally the lower ones again 2–7-branched; unit conflorescence cylindrical, 7.5–10 cm long, acropetal to subsynchronous. Flowers irregularly acroscopic. Flower colour: perianth and style creamy white to pale yellow, rarely creamy pink. Perianth subsericeous to subvillous or sparsely so to almost glabrous outside, bearded near base inside or rarely glabrous. Nectary U-shaped or annular. Pistil 5–11 mm long, glabrous; pollen-presenter very oblique, broadly conical. Follicle compressed oblong-ellipsoidal with a decurved apiculum, (8–) 11–16.5 mm long, glabrous, usually faintly viscid when young, smooth at dehiscence, crustaceous with exocarp flaking away soon after maturity to reveal pale mesocarp. 

Occurs in all mainland States except Vic., widespread in arid areas: in W.A. in the Gibson and Great Sandy Deserts and near the coast from Shark Bay to Onslow; in N.T. southwards from Tennant Creek; in S.A. in the NW third of the State; in Qld W from Charleville and Windorah; in N.S.W. in the far NW corner only. Grows in red sandhill country with shrub and Triodia communities. Flowers May–Dec. Map 372.

W.A.: Gascoyne Junction, N.H.Speck 1507 (AD, CANB, PERTH). N.T.: 43.5 km N of Barrow Ck, N.Forde 216 (AD, CANB, DNA, MEL, PERTH). S.A.: 11.3 km N of Emu, N.Forde 499 (CANB, MEL, NSW). Qld: 48 km W of Charleville, 8 Sept. 1968, G.Bates & Rose (QRS). N.S.W.: Binerah Downs, between Fort Grey and Waka, P.L.Milthorpe 552 (AD, NSW).

There is considerable variation in several features, and further research is warranted. Some populations between North West Cape and about Coral Bay in W.A. have divided leaves, which are very rare elsewhere. Most populations between Binnu and Shark Bay, W.A., have very small fruits (8–9 mm long) and small flowers (pistils 5–6 mm long); these features are only partially correlated with divided leaves. Nectary structure is annular in some W.A. plants and perhaps populations. Longer ovarian stipes occur in the Gascoyne R. area of W.A. Indumentum on the outer surface of the perianth is denser in the west of the range; flowers are largest in the Tanami area of N.T., and smallest at the southern end of the range in W.A. (Hamelin–Tamala area) where the inner surface of the perianth is also glabrous (elsewhere always with some hairs).
